FOUL-SEED EXTRACTCR AND RECLEANERJ SPECIFICATION forming part of LettersPatent No. 542,337, dated July 9, 1895.

Application filed November 16,1894. Seria1N0- 29;039- (No model.)

ANSON H. WILLIAMS, citizens of the United States, residing at Delta, inthe'county of Fulton and State of Ohio, have invented a new and usefulFoul-Seed Extractor and Recleaner, of which the following isaspecification;

This invention relates to foul-seed extractors and recleaners for grainthrashers or separators; and it has for its object to provide a new anduseful machine of this character adapted to be used in connection withan ordinary thrasher or separator to provide efficient means forthoroughly extracting or separating foul seeds from wheat, oats, andother grains that have passed through an ordinary thrasher, and toreclean such grains, in order to produce the finest possible gradesthereof.

With these and other objects in View, which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the drawings, Figure 1 is:a perspective view of a machine constructedin-accordance with this invention. Fig.2 is 'a central longitudinalsectional view thereof. Fig. 3 is a transverse vertical sectional viewon the line m as of Fig. 2. Fig. 4is a central longitudinal sectionalview of the upper part of the machine, showing the adjustableskimmingapron adjusted with one end thereof disposed within one end ofthe uppercleaning-shoe. Fig. 5 is adetail in perspective of theadjustable skimming-apr'on; Fig. 6 is a similar View of the stationarysieve-cleaner for the upper vibrating cleaning-shoe.

Referring to the accompanying drawings, 1 designates the casing of themachine, essentially comprising the opposite parallel casing sides 2,suitably connected'together at different points by the transverse tierods or bolts 3, and arranged to work within the upper part of the opencasing 1 is the upper vibrating cleaning-shoe 4. The upper vibratingcleaning-shoe 4 is substantially rectangular in shape, and is of alength nearly equaling the length of the casing, within which the saidshoe has a combined reciprocatory vibrating movement, and the saidvibrating shoe is crank-shaft 12. 12 is'journaled in suitable bearings13 at opadapted tobe arranged under the upper discharging end of theusual elevator-spout of an ordinary grain-thrasher orseparating-machine. To secure this disposition of the upper vibratingshoe to receive the grain from the thrasher or separator,theherein-described machine is preferably placed directly on a side of thethrasher or' separator.

The upper vibrating cleaning-shoe 4 has attached to the under sidethereof, near one end, the transverse supportingbar 5,provided with thespindle extremities 6, loosely engaging in the lower ends of thehanger-links 7, pivotally secured at their upper ends at8 to 0ppositesides of the casing 1, near one end there of, to provide for supportingone end of the shoe for a swinging movement, and loosely connected tothe shoe 4 at an intermediate point, as at 9, is one end of anoperating-pitman 10, the other end of which is connected to anintermediate crank 11 of the transverse The transverse crank-shaftposite sides of the casing, and upon one extremity'of said shaft,outside of the casing,

may be mounted a belt wheel or pulley 14, that'receives a belt from anysuitable driving source, such as one of the wheels orpulleys of thethrasher or separator, in connection with which the machine is employed.

The vibrating shoe 4 is provided at a point intermediate of its endswith a bottom seedpocket 15, having the declining sides 16, that:connect with a laterally-inclined chute-board 17, forming thebottomof'said pocket and leading into a short offstanding chute 18. Theshort ofistanding chute 18 is attached to one side of the bottomseed-pocket of the upper vibrating shoe and projects through'and worksin a chute-slot 19, formed in one of the casing sides, and said chuteserves to discharge the foul seed and other separations from Wheat,oats, or other grain into the upper end of aside discharge-spout 20,arranged at one side of the machine-casing and serving to discharge thefoul seed and other similar the construction in which the meshes of thesieve are made up of a series of closely-arranged slots, and the meshesof the sieve 21 are sufiiciently fine to prevent the wheat, oats, orother grain being separated from passing therethrough, while at the sametime providing for the separation of the foul seed and other impuritiesfrom the good grain and the discharge of such foul seed or otherimpurities into the bottom seed-pocket already referred to.

The fine-mesh separating-sieve21is adapted to have the frame thereofsnugly register within the shoe 4 and to rest flat on the bottomthereof, and adapted to be arranged between the sieve 21 and the bottomof the shoe 4 is the stationary rectangular sieve-cleaning frame 22. Thestationary sieve-cleaning frame 22 is of a shorter length than the shoeand the sieve 21, so that as the shoe is vibrated or reciprocated theframe 22 will be held to a position to scrape or contact gently with theunder side of the sieve 21, that works thereover, and thereby providingmeans for keeping the meshes of said sieve clean and also for workingthe foul seed and other separated impurities from the fiat floor of theshoe into the bottom seed-pocket 15. The sieve-cleaning frame 22 isprovided at both sides of its center with a series of transverse cleanerbars 23, that perform the double function referred to of cleaning thesieve and working the separations into the bottom seed-pocket, and thesaid frame 22 is secured on top of an adjustable transverseframe-support 24. The adjustable transverse frame-support 24 comprises aseries of connected parallel framebars 25, that allow the separations tofall freely therebetween into the seed-pocket, and said frame-support isarranged inside of the pocket 15 and is provided at its under side withthe rod-lugs 26, that loosely receive the a transverse bolt-rod 27, thethreaded extremities of which project through aligned slots 28 inopposite sides of the upper vibrating shoe and of the casing, and on theoutside of the casing sides. The threaded ends of said bolt-rod receivethe thumb-nuts 29, that serve to clamp the frame-support 24 fast in anyadjusted position, whereby any wear on the frame 22 may be readilycompensated for and the same always maintained properly adjusted tosecure the results noted. The boltrod 27 not-only provides means for thevertical adjustment of the cleaning-frame 22, but at the same timeloosely supports such frame in position, so that it will readily adjustitself to the vibrations of the shoe.

To provide for properly supporting the machine in position to disposethe sieve of the upper shoe under the discharge from the thrasher orseparator, opposite pairs of vertically-slotted bracket-plates 33 aresecured to the opposite under sides of the casing 1. bracket-platesextend above the upper edges of the casing and are adapted to beadjustably bolted, by means of the bolts 32, to suitable hangers 31,arranged at one side of the thrasher or separatorto provide for thesupport of the extractor and recleaner.

In the recleaning of oats and similargrains the sieve 21 is the onlysieve employed in the upper vibrating shoe, butin recleaning wheat aremovable overflow-sieve 30 is employed. The removable overflow-sieve 30is rectangular in shape to removably register within the shoe 4 overthesieve 21, and the said removable overflow-sieve may consist of anysuitable coarse-m esh sieve of a rectangular shape and of a lengthexceeding the length of the vibrating shoe 4 and of the casing l, andone end of the long sieve 30 projects beyond one end of the shoe 4 toprovide for discharging joints, straws, and other coarse material beyondone end of, the machine, so that the grain will be relieved from. suchmaterials and will pass to the sieve 21 in a partially-cleanedcondition.

The open discharging end of the upper vibrating cleaning-shoe 4 isarranged to slide on top of the upper horizontal rest-bar 34 at theupper inner end of the segmental graingrating 35. The said segmentalgrating consists of a series of parallel curved grating wires or bars36, connected at their upper and lower ends, respectively, by thehorizontal rest-bar 34 and the lower grating-bar 37, said bars 34 and 37being fitted securely within the casing 1 at one open end thereof.Arranged directly under the upper ends of the wires or bars 36, adjacentto the outer edge of the rest-bar 34, is the longitudinallyflutedgrainroller 38. The longitudinally-fluted grain-roller 38 is mounted ona transverse roller-shaft 39, journaled transversely within the casing1, and carrying upon one end, outside of the casing, the belt Wheel orpulley 40, over which passes one portion of a belt4l, that serves tocommunicate motion to the roller 38 in the manner to be presentlyreferred to.

As the wheat, oats, or other grain is worked off from the sieve 21,through the open end of the shoe 4, such grain falls over the restbar 34onto the grain-roller 38, which evenly and regularly drops the graininto the space below the same and confined within the grating 35, and asthis operation takes place the grating itself serves to throw off at oneend of the machine the coarse stuff or tailings, and the grain is keptclose to the wires or bars of said grating by meansof an inclinedgrain-board 41", supported at an angle between the opposite frame sidesdirectly over and near the grating at a point intermediate of the upperand lowerends thereof.

\Vhen the machine is used without the overflow-sieve 30, as clearlyillustrated in Fig. 4 of the drawings, in working oats an adjustableskimming-apron 42 is adapted to be.used in connection with the opendischarging end of the upper shoe 4.

The adjustable skimming-apron 42 essentially comprises a parallel seriesof angular wires or bars 43, connected at their opposite ends by thetransverse apron-bars 44, and the I said connected wires or bars 43 aresecured arranged for adjustment at one end of the site sides of thecasing l.

casing 1, and when in use is adjusted to a position to bring one of thetransverse bars 44 inside of the open end of the shoe 4, directly aboveone end of the sieve 21, and in this position the said apron will skimoff all coarse straws and similar stuff and discharge the same out atone end of the machine, while at the same time allowing the oats to passthrough the grating onto the fluted grainroller 38. As the grainjallsfrom the fluted grain-roller'within the grating 35, the same falls ontothe inclined cant-boards 46, that are arranged transversely within thecasing 1 below the grating 42 and serve to guide or deflect the graininto one end of the lower vibrating cleaning-shoe 47, that is arrangedto work within the lower-part of the casing 1. During its passage ontothe lower cleaningshoe 47 the grain passes across a wind-blast fromtherotary fan 48. The rotary fan 48 is mounted to revolve within a circularfan-casing 49, arranged within the casing between the upper and lowershoes, and saidfan is mounted on a transverse fan-shaft 50, journaled inopposite sidesof the casing and having nounted on one extremity thereofa beltpulley 51, over which passes the lower portion of the belt 41,that communicates motion to the roller 38in the manner described.

The circular fan-casing 49 is provided in one side thereof with ablast-opening 52, that is designed to be covered and uncovered by acurved wind-door 53, The curved wind-door 53 is arranged to work on theoutside of the casing 49 and is attached at its lower edge to atransverse adjusting bolt-rod 54, the threaded extremities of whichproject through and work in the curved slots 55, formed in oppo- Ihethreadedextremities of said bolt-rod 54 outside of the casingare engagedby the thumb-nuts 56, that provide means for holding the door 53 in anyadjusted position to provide for-the proper regulation of the blastdischarged through the blast-opening 52. The blast from the fan 48 doesnot pass through either of the shoes, but only through the grain thatfalls from the upper to the lower shoe and serves to free such fallinggrain from lightimpurities. Beyond the space between the adjacentinclined cant-boards 46 is arranged an adjustable tailings-board 57. Theadjustable tailingsboard 57 is pivotally mounted at one edge, as

at 58, between the opposite casing sides 2 at one end of the casing, andconnected to one end of the adjustable board 57'- is an adjusting-screw59, working in the longitudinal slot of the longitudinally-slottedadjusting-arm 60, pivotally secured at its inner end, as at 61,

to one side of the casing 1 on the outside thereof. By loosening thescrew 59 and adjusting the arm 60 the board 57 may be properly adjusted,with respect to the wind-blast, to provide for catching the tailings orlight impurities blown out from the falling grain, and to directsuch'tailings into the end tailings-spout 63, formed within the casing 1at one lower end thereof.

The lower vibrating separating-shoe 47 13 of substantially the sameshape and size as the upper shoe 4, and said lower shoe has attached tothe under side thereof, near one end, the transverse supporting-bar 63,provided with the spindle extremities 64, loosely engaging in the lowerends of the hanger-links 65, pivotally secured at their upper ends, asat 66, to opposite sides of the casing 1, near one end thereof; At anintermediate point the lower shoe 47 has loosely connected to the topthereof one end of the operating-pitman 67, the other end of which isconnected to the intermediate crank 68 of the transverse crankshaft 69.'The transverse crank-shaft 69 is journaled transversely in the casing 1above the lower shoe 47, and has mounted on one extremity thereof,outside of the casing, a beltwheel 70, over which passes a portion ofthe belt 41, and alongside of the belt-wheel 70 is mounted a gear-wheel71-, that meshes with a similar adjacent gear-wheel 72, mounted on oneend of the upper crank-shaft 12, to provide a connection for transmitingmotion to the various working parts of the machine from said uppercrank-shaft, as will be readily understood.

The lower vibrating shoe 47 is provided with the oppositely-inclinedbottom boards 73, that decline to an intermediate bottomdischarge-opening 74 to provide. for the dis charge of the finalseparations from the good grain on the fine-mesh separating-sieve 75,that is arranged within the bottom part of the shoe 47, and effects anyseparation that the sieve 21 in the upper shoe fails to effect.Ordinarily the sieve 75 is employed alone in the shoe 47, as alreadydescribed in connection with the upper shoe; but in recleaning wheat acoarse-mesh long overflow-sieve 76, similar to the sieve 30, isemployed. The coarse-meshlong overflow-sieve 76 is removably arranged inthe shoe 47 over the sieve 75, and one end of the sieve 76 projectsbeyond the open end of the shoe 47 and subserves the samefunction as thesieve 30 already referred to. The good grain that is worked over thesieve 75 is discharged at the Y open end of the shoe 47 into the upperend of the transverse hopperbox 77. The transverse hopper-box 77 isarranged at one end of the casing 1 under the open discharging end ofthe shoe 47, and is provided with the branch grain-spouts 78, that serveto alternately discharge the grain into bags connected therewith in theordinary manner, and arranged centrally within the hopper-box 77 is apivoted valve-gate 79, that is adjusted at one end of the box 77 bymeans of a suitable valve-lever 80 to alternately close and open up thespout 78.

From the foregoing the construction, operation, and many advantages ofthe hereindescribed machine will be readily apparent to those skilled inthe art, and it will be understood that changes in the form, proportion,and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the ad vantages ofthis invention.
